As illustrated in Figures 1 m4, inclusive, of:the drawings, the machineis provided with a'base 10 on which is secured from and rear pairs offrame members oruprights 11 and 12, the upper end sections-of theuprights having secured thereto spaced upper and lower platforms 13 and14, respectively. Secured between the platforms are vertical adjustablebearings 15 disposed above bearings 16 carried by the base, the bearings15 and '16 having rotatably mounted thereon pulleys 17 and 18,respectively, disposed in paired relation one above the other.

ends-of actuating rods-53s Therodvare-provided, be-

tween'the standards and the'brackets, with front and rear plates-54 forfolding a-wrapper-,--depositedon the upper runs of the chains, about theroll. Coincident ends of the rods have fixed thereto sprockets 55, overwhich are trained "chain section's' 56' for operating the sprocketswhereby the plates are actuated-from their open or "upright positions,as shownfin dotted linesin Figure'3, to folded or horizontal positionsas shown in full-lines, the

rearplate being disposed above the front plate. The ends V deposit ontothe conveyor-and'whichreceptacle is provided'with'an open front end andbottom and rear walls 61 and 62, respectively; A wrapper retainer 63 issecured in sliding engagement with thefrearwall 62 and has its upper endprovided with an angled end section overlying the rear endsofthewrappers-WJ The ends of the angled end section are equipped withblocks'in which are secured pins, one of which is illustrated at 64,having their lower ends relatively sharp and penetrating a plurality ofthe uppermost wrappers fora purpose hereinafter more fully described. 7I i An'adhesive distributor overlies the wrappers W and comprises areservoir 65 formed with apair of forwardly extending arms'66 fixed to'a supporting shaft 67 journaled in the brackets 31' and'on whichshaft isloosely mounted a pair of relatively fixed sprockets 68. The rear end ofthe reservoir 65 is provided with 'an'adhesive applying roller orapplicator 69 constructed of suitable material, for instance, rubber,formed about and fixed to a drive shaft 70. The roller 69 functions toapply adhesive to the rear marginal area of the uppermost wrapper Wdisposed immediately subjacent the reservoir. The roller extends throughan openingformed-in the bottom wall of the reservoir and is engaged by adistributor plate 71 adjustably secured to the bottom wall by means ofscrews extending through elongated apertures provided in the plate. Theface of the plate, which engages the roller, is slotted, the slots beingof a width and depth to permit a desired quantity of the adhesive A,contained in the reservoir, to be distributed by the roller onto theuppermost wrapper NV through the opening upon rotation of the roller.The shaft 70' of the roller is provided with a sprocket 72 connected toone of the pair of sprockets 68 by means of a chain- 73, the othersprocket of the pair being connected to a-sprocket'74 by means of achain 75. The sprocket 74 is fixed to the shaft 32 whereby the roller69-is rotated when the retaining belts are operated. Also fixed to theshaft 32 is a cam-76 for operating a cam arm 77 fixed to the shaft 67and which functions to raise and lower therear end of the reservoir androller out of and into engagement with the wrappers W.

In operation, assuming that plates 54 to be in open position and theroller 69 is disposed out of engagement with the uppermost wrapper whichhas previously been supplied with adhesive, the uppermost wrapper isgrasped by the fingers of the operator and moved outwardly from thereceptacle 60 and positioned upon the upper run of the conveyor betweena pair of the flights and the plates 54 as illustrated in dotted'linesin Figure 3. As the uppermost wrapper is thus withdrawn, the rearcorners are ruptured by the pins 64 to effect release of the Wrapperthus permitting the weight of the retainer to insure further penetrationof the pins into another of the uppermost remaining wrappers for holdingthe latter during application of adhesive. When the wrapper has thusbeen disposed on the conveyor, a roll 30 is disposed within the wrapperand the treadle operated to actuate the plates to their folded positionsas illustrated in full lines in Figure 3,

thus enfolding and sealing the roll the wrapper.

As the conveyoradvances, the treadle is released to permit the plates to return totheir open positions while the roll, which is now enfolded in thewrapper, is conveyed into engagement with the lower runs of the beltsand retained As the conveyor and belts advance, the rolls aresuccessively severed by the knife sections into relatively shortlengths, thus, forming the toilet paper rolls or packs.

As diagrammatically illustrated in Figures 5 and 6 of the drawings,automatic mechanism may be employed for feeding the wrappers W from thereceptacle 60 into position on the conveyor for wrapping about the rolls30. The mechanism comprises a'pair of arms 80 each formed at its upperend with an angularly disposed section and wvith a longitudinallyextending slot or track 81 terminating in a seat 82 in the section. Theslots 81 have mounted therein flange rollers 83 journaled on the ends ofa transverse hollow shaft 84 connected by means of a flexible tube 85 toa negative source of pressure. The

hollow shaft 84 has pivotly connected thereto and in 7 described. Thelower ends of the arms 80 are connected together and provided withtrunnions 87 journaled in the standards 24 and on which are looselymounted pairs of relatively fixed. sprockets 88, one sprocket of eachpair being connected to a similar sprocket 89, mounted on the upper endof each arm, by a chain 90 which is provided with a dog 91. The othersprocket of each pair 88 is connected to one of apair of sprockets 92fixed to a shaft 93 also journaled in the standards 24. The shaft 93 hasone end provided with a spur gear 94 meshing with a spur gear 95 looselymounted "on a stub shaft 96 carried by one ofthe standards 24. The spurgear is fixed to a sprocket 97 also loosely mounted on the stub shaftand connected with a sprocket 98, fixed on the shaft 26, by means of achain 99. One of the trunnions 87 has fixed thereto the upper end of acam arm 100, the lower end of which is provided with a roller 101engaging a cam 102 mounted on the shaft 26 of the conveyor.

In operation, assuming the cups 86 are in engagement 9 with theuppermost wrapper as disclosed in full lines in Figures 5 and 6,.and theconveyor shaft 26 is being rotated, the cam 102 serves to pivot andraise the arms 80 towards a vertical position and away from thereceptacle 60 and with the chains 901being operated through the sprocketand chain assembly heretofore described. As the arms 80. arethusrotated, the uppermost wrapper will be detached from the other wrappersand moved outwardly from the receptacle. As the arms 80 continueto moveaway from the receptacle, the hollow shaft 84 will be engaged by thespring fingers 103 fixed to the brackets 31 and force the rollers 83 outof the seats 82, whereupon the shaft 84 and rollers 83 will begravitated downwardly to the lower ends of the arms 80 and thus carrythe wrapper downwardly. This action results in the wrapper beingcompletely withdrawn from the receptacle and deposited upon the conveyorand between the plates 54 as shown in dotted lines inFigure 5. When thewrapper has thus been positioned, a valve (not shown), connected betweenthe cups 86 and the source of negative pressure, operates to break thepressure and release the front ends of the wrapper from the cupswhereupon a roll of paper maybe placed within the wrapper andbetween'the plates 54.

mit engagement of the cups 86 with the next uppermost wrapper forshifting the latter to the conveyor in the foregoing described manner.

From the foregoing it will be apparent that my invention provides arelatively simple and compact machine wherein the use of endless cuttingbands for the severing of major rolls into short minor rolls ispermitted due to arrangement of the bands with respect to the conveyorand retaining means.

Without further elaboration the foregoing will so fully explain theinvention that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service. Moreover, it isnot indispensable that all the features of the invention be usedconjointly since they may be employed advantageously in variouscombinations and subcombinations.

It is obvious that the invention is not confined to the herein describeduse therefor as it may be utilized for any purpose to which it isadaptable. It is therefore to be understood that the invention is notlimited to the specific construction as illustrated and described as thesame is only illustrative of the principles of operation, which arecapable of extended application in various forms and the inventioncomprehends all construction within the scope of the appended claims.
